| Research Abstract |
The giant dipole resonance (GDR) in 6Li was investigated via the 6Li(gamma,n) reaction.The GDR in 6Li was found to consist of two components at Ex= 15 MeV and 33 MeV. The component at Ex=15 MeV is seemed to be the intrinsic GDR in 6Li. The another one at Ex=33 MeV is due to the GDR of the alpha cluster in 6Li. Since the GDR in free 4He is known to locate at Ex= 27 MeV, the excitation energy of the GDR of the alpaha cluster in 6Li is much higher than that of the 4He. This fact suggests that the size of the alpha cluster in 6Li is smaller than that of 4He due to the nuclear medium effect.
